Scientific paper

We present Washington photometry of the unusual metal rich globular cluster NGC 6441. Using the available IRAS maps and independent reddening measurements, we model the effects of variable interstellar extinction. This process reduces the uncertainties in the age and metallicity estimates of the cluster population. We compare the stellar content of the cluster with that of NGC 6388, which also has a horizontal branch with both a red clump and an extended blue tail. These are the only two relatively metal-rich clusters that exhibit this trait, which may be due to variations in age, metallicity or helium content, mass loss, or rotation effects.
